Some interesting ideas in our DF

45 deg to the horizontal, is it?

Perhaps his speed must be fast to propel him forward.

The wind direction could probably be in his favour.

Some of the possible factors may be running speed, length of strides and landing techniques.

a possible factor affecting the distance: the direction of the force the jumper exerts.

Putting our knowledge together

This is what we understand about forces at this moment
Group X	the force must have come from the spoon and pushes the melon forward.
